In their own words
MASV
MASV is a managed file transfer service for sending, receiving, and automating delivery of large files. It supports web, desktop, API, Linux, macOS, and Windows access. Transfers can resume after interruptions using checkpoint restart, and branded browser portals can route contributor files to one or multiple destinations. The desktop app includes channel bonding, real-time uploads of growing files, and transfer optimization for 10 Gbps+ connections. Listed integrations include Amazon S3, Backblaze, Box, Dropbox, Frame.io, Google, and IBM Cloud Object Storage. MASV says transfers use TLS 1.2+ encryption in transit and AES-256 at rest; its controls include SAML-based SSO, MFA, role-based permissions, password protection, download limits, and expiry dates. On-Demand includes 15 GB of transfers free each month, then charges $0.25 USD/GB, and requires a credit card. Files are stored free for five days, then cost $0.07 USD per GB per month. MASV was founded in 2019 and is headquartered in Ottawa, Ontario, Canada.
